[. . . ] B 13 1. 9 Drive acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are generally consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward. Typical sound power (bels) 3. 7 4. 1 Maximum sound power (bels) 4. 1 4. 5 Mode Idle Seek (read/write) 1. 10 Electromagnetic susceptibility The drive operates without errors when subjected to the following: Radiated noise Electrostatic discharge* Magnetic field strength 3 volt/meter, 30 to 1 GHz 10 KVolts 5 Gauss * Electrostatic discharge susceptibility is measured with the drive mounted in a representative computer system (mounted to a ground plane with earth grounding). Discharges are applied to the bezel or other external surfaces on the ground plane. 1. 11 Reliability Nonrecoverable read errors Mean time between failures 1 per 1014 bits read, max 300, 000 power-on hours (nominal power, 25°C ambient temperature) 40, 000 cycles (at nominal voltage and temperature, with 60 cycles per hour and a 50% duty cycle) None required Contact start-stop cycles Preventive maintenance 14 Medalist 1720 Product Manual, Rev. B 1. 12 Agency certification 1. 12. 1 Safety certification The drive is recognized in accordance with UL 478, UL 1950 and CSA C22. 2 (950) and meets all applicable sections of IEC 950 and EN 60950 as tested by TUV North America. 1. 12. 2 Electromagnetic Compatibility Hard drives that display the CE marking comply with European Union requirements specified in Electromagnetic Compatibility Directives. Testing is performed to standards EN50082-1 and EN55022-B. Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products. 1. 12. 3 FCC verification This drive is intended to be contained solely within a personal computer or similar enclosure (not attached as an external device). As such, each drive is considered to be a subassembly even when it is individually marketed to the customer. As a subassembly, no Federal Communications Commission verification or certification of the device is required. has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc. ) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interference to radio and television reception. This equipment generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this Medalist 1720 Product Manual, Rev. B 15 equipment does cause interference to radio or television, which can be determined by turning the equipment on and off, you are encouraged to try one or more of the following corrective measures: · Reorient the receiving antenna. [. . . ] B 3. 2. 3 Set Features command This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write caching features enabled and 4 bytes of ECC. [. . . ]
